Migrate content from Joomla 2.5.4 to Drupal 8

Hello everyone.

By obligation of the client, wants to make a new Web in Drupal8.

Currently they have Joomla, version 2.5.4

Is it possible to migrate directly from Joomla 2.5.4 to Drupal 8?

I think not, therefore, I have mounted a Drupal 7 and I used the module “Joomla to Drupal” to migrate the contents, but failed, because it did not go for Joomla 2.5

I used the patch discussed here: https://www.drupal.org/node/2262043

And after applying it, I migrated “some” users (not all), and content, only the privacy policy page, the rest did not.

How can I migrate all content correctly?

Thank you.

Drupal version:
